A pixel-perfect Android chat screen for an AI assistant app in dark mode with neon accent styling. Background is near-black (#121212). The top app bar shows a circular AI avatar with a pulsing cyan ring, the name "NOVA" in a techy condensed sans-serif, and a subtitle "Online · Thinking...". The conversation shows three message bubbles: two user messages in rounded rectangles with a deep charcoal background (#2A2A2A), and one AI response bubble in a slightly lighter surface with a left neon cyan border strip (3px). The AI response text explains a concept in two paragraphs — the second paragraph highlights a key phrase in neon cyan bold. Below the bubbles, a streaming indicator shows three animated dots in cyan. The input bar at the bottom is a flat dark surface with a rounded text field reading "Ask anything..." in muted gray, a microphone icon (left), and a glowing cyan send button (right). The keyboard is not visible — focus is on the message thread. Android material icons throughout.
